Specification of Letters Patent.

PatentedMar. 25, 1913.

a To all whom it' concern Be it known that I, IRvrNc'BLotnsr, a citizenof the United States, the borough of Brooklyn, city and State of NewYork,- have invented certain new and useful Improvements in Separators,of which the following is a specification.

This invention relates broadly to apparatusfor separating liquid andsolid constituents of a material containing both, and more particularlyto apparatus for. extracting oil, grease, water, etc., from garbage orother matter.

In a general way it may be stated that one of the important objects ofthe present invent-ion is to provide a digester or separator which willecoof liquid and solid matters, nomically separate said materials fromeach other and will reduce the time incident to the discharge of thesolid residue-to a miniand others which will construction illustrated inthe accompanying drawings to exemplify what is regarded to be the bestembodiment of the invention but to the details of which the invention isnot, considered in its broader aspects, restricted, aschanges-may-bemade in the de-' tails and the essential features of the inventionwithout. departing from the spirit of the invention or the scope of thesubjoined claims."

In the drawings, wherein like characters of reference denotecorresponding partsz' Figure 1 is a longitudinal view partly inelevation and partly in section of a digester or separator containingthepresent improve ments. Fig. 2 is a vertical transverse sec tion thereofon'the line 2-2 of'Fig. 1. Fig. 3 is a vertical transverse section on aline corresponding to the showing the digester open of its contents. 7

The container A comprises an outer wall 1 and an inner wall 2 arrangedin a spaced relation and separated from each other by stiffening andspacing members 3 which .extend transversely thereof. Preferabl thecontainer is of cylindrical form, as s own. The inner wall 2 isperforated as "shown, or is otherwise such .as extracted from thematerial undergoing treatment and the fluid which is employedto'causesuch extraction to flow therethrough into the space 4 arrangedbetween the walls for the discharge and a resident ofline 3-3' of Fig.1,

' edes thereof.

to permit the liquid 1 and 2. Solid heads 5 and 6 are provided at theends of the container. These heads are preferably of concavo-convex formand obviously they form partsof theouter wall of the container. Thetreating chamber B, en-

circled by the inner wall 2 of the container,

has its ends provided with plates 7 which are arranged at the ends ofthe wallsQ and areperforated or otherwise formed'to permit the fluids topass therethrough' into the heads 5 and 6 respectively. The heads 5 and'6 are provided with internal bracing members 9 and 10. a

As shown most clearly in Figs. 2 and 3 'the container A is formed toprovide an outer section A and two lower sections A A each having theinner and outer walls 1 and2 hereinbefore described. Each of thesesections preferablyextends throughout the entire length ofthe'treating-chamber Band they-are complementary to each other, servingwhen closed to form said treating chamber. The section A is hingedlyconnected at 11 to the bottom of the section A at one side of the latterand the section A is'simi larly hingedly connected, at 12, to the bottomof said section A at the opposite side of'the latter. Theconfrontingedges of the sections A and A are provided with means whereby they ma besecurely locked together' to. enable t e treatment of gmaterial to becarried on therein and whereby also they may be readily opened out forthe discharge of the solid matter, that is, the residue left after theliquid content of the material has been removed from said material.

This fastening means preferably consists of a series of pivoted bolts 13which enter apertures in the flanges 14 projecting from members15 whichextend longitudinally of the respective sections A and A and stiffen theThe lower edges of the sections A and. A are each further stiffened bymembers 16,-which thereof and are arranged between the outer and .innerwalls 1 and 2 and serve also to close said edges. The opposite edges ofsaid sections are similarly, closed and stiffened by members marked 17.Each journal of the hinges 11 and 12 is'pre'ferably carried bycomplementary angle irons 18 and 19 secured to the confronting portionsof the members A and A or A nally of the latter'and serving to st-i enthe construction at this place. Fastening bolts extend longitudinallyopen a suitable liquid which flows through 40 a per is provided thewalls2 of the sections reaches the heads 5 and 6.

20 are prefer'ably provided to hold the two serve to convey theextracted liquid to the heads 5 and 6 and said heads are provided with.drain pipes 22 and 23 by which said liquid is carried off to any desiredplace.

' drum or hopper C is arranged above the container A and opens into thetreating chamber B .of the latter. This drum or hopwith a valve D havinga hand wheel or other suitable means (i for operating it. At aplacebet-ween the valve D and the mouth act the hopper or drum 't-he're'isarranged an inlet pipe E for the steam or other fluid which is employedto separate the liquid content of the material from the solid matterthereof.

From the foregoing the operation of the invention will readily beunderstood to be as follows: The sections being in the position shown inFig.2 and the valve D being quantity of material is introduced throughthe drum or hopper G into the treating chamber B. The valve D is thenclosed and steam or other selected fluid is admitted through the pipe E.This fluid is preferably under pressure suflicientto compactthe-material as well as being of a nature which extracts the liquidmatter from the latter. The extractedmatter and the fluid employed forthe extraction flow through and through the perforated end wall 7. Thatportion of the upper section A enters passages between the spacingmembers 3 and flows to the troughs 21 and 22 and thence into the heads 5and 6. A portion of the fluid also flows through the plates 7 into saidheads 5 and 6: and such portion as flows through the walls 2 of thesections A and A ultimately The spacing members 3 are apertured whereverit is necessary to provide for the intercommunication of the theliquidmay be'permitted to flow 'to'said heads. When the liquid contentof thematerial which has been placed in' the chamber B has been extracted fromsaid material, the residue will be found to'be closely compacted in thebody of the container. The flow of treatingflfiuid is then cut off, thevalve D is opened and more material. is supplied .to the chamber. Thisis treated in the manner already described and thissequence ofoperations is repeated until it becomes expedicut to remove the solidresidue from the treating-chamber. .In order to permit this removalit isonly-necessary to release the sections A and A from each other and tothe walls of the -I believe to be new spaces between them in order thatswing them oppositely on their hinges 11 and 12 to the position shown inFig. 3. When this has been done the interior of the treating chamber Bwill be fully exposed and will be open downward. The solid matter willtherefore be freely andquickly discharged from said chamber. Thisdischarge may be effected wholly by gravity, but if it is considered tobe desirable, gravity may be assisted by the introduction into thechamber of air or other suitable fluid under pressure, drawn from asuitable source of supply. This discharging fluid maybe supplied by apipe F. If desired, the treating fluid may be employed to aid in thedischarge of the solid material, but it is considered to be preferableto employ a separate fluid. Apparently also, even when a separate fluidis employed it may be introduced through the same pipe which is employedfor the introduction of the treating fluid, by connecting the dischargeend of the latter wlth the separate sources of supply to the treatingfluid and discharging fluid.

In the'use of the apparatus, it is preferred to supply a charge ofmaterial suflicient in quantity to reach up into the drum to a placeimmediately below the pipe E and to cutoil the supply of fluid and renewthe charge when the previously-introduced charge has been compacted to aplace at or immediately below the upper rows of perforations in theinner walls. This avoids waste of treating fluid. Preferably, the innerwalls of the container are free from perforations at the top in orderthat the material may be compacted to a place below'the top of thelatter, before renewing the charge.

Preferably the'apparatus is provided with brackets G by which it 1ssupported in a suspended relation.
